Anyone here have one of these? They seem amazing and the one review I've read on it has nothing but praise.

Re: Alexander Arms 17HMR AR
they are great little guns, Bill did an excellent job in designing that rifle and it shoots pretty good too

Re: Alexander Arms 17HMR AR
I'd like to see some close up pics of the fired casings out of one of these uppers before I form an opinion. A blow back operated HMR is just asking for ruptured cases and injured shooters. If a guy was to create a gas impingement or gas piston system for the HMR, it would be a much safer setup.

Remington posted a recall notice regarding 17 HMR in last American Rifleman - don't use their ammo in Semi-autos, and return your Model 597 17 HMR rifle for replacement....

Yes. But after much investigation, they figured out the problem and it is essentially only an issue in the Rem 597.

Then Remington adapted their Model 597 autoloader to the .17 HMR… and that’s where the trouble began. The .17 HMR’s pressure and thin case didn’t adapt too well to the Remington 597. First designed to handle a .22 long rifle, the 597 used a steel bolt in a blow-back mechanism. No problems here. When the .22 WMR design was adapted to .17 HMR, Remington engineers opted for a heavier tungsten/nickel/iron matrix bolt to retard the speed of the blow-back mechanism. But, tungsten, though heavier than steel, is more brittle. Another problem with tungsten is that it has an inherent variability in specific gravity that makes a final part’s hardness a moving target. It was just a matter of time until something went wrong.
By its very nature, rimfire ammunition is rather dirty. We all know that rapid shooting heats up a rifle barrel, too. Combine the two issues within the confines of a .17 HMR case and it’s to be expected that pressure will spike, and occasionally a case will fail. When a .17 HMR case ruptures in a Remington 597 catastrophic failure occurs. The hot propellant gases ride the cuts in the tungsten bolt and shatter it, which have led to shooter injuries and lawsuits. “The AR is so massively overbuilt that it just keeps on ticking,” Alexander said, “whereas the 597 blows up.” Other stronger semi-auto designs seem to be withstanding the pressure.
Remington was quick to issue a total recall of their Model 597s chambered in .17 HMR. Ruger has also stopped making available their 10-22 magnum .17 HMR versions. On the other hand, Volquartsen hasn’t stopped making their TF-17 semi-autos. They must feel that their semi-auto design is built to handle the .17 HMR without problems.</div></div>

It was not designed to be shot in a blowback configuartion, but if the gun is built with good materials, even a case rupture will not harm either the gun or the user, and can be completely avoided if not run hot and dirty.

Re: Alexander Arms 17HMR AR
I dunno. 17's run a little too hot for me to feel comfy firing one semi no matter where the ammo comes from. JMO.

Re: Alexander Arms 17HMR AR
Absolutely perfectly safe. We shot at least 1K rounds through Bill's up in Kansas and never a problem. I have spoke with the guy at Hornady responsible for the 17HMR development and there is absolutely no problem with it.

Weird.
I'd swear the Remington warning said otherwise.

Call Dave Emery up @ Hornady and get his thoughts on it? Nothing in those two paragraphs says anything about the AMMO being unsafe. Just says that ask the manf. of your gun. You can PM me if you would like.
We are not firearms manufacturers and we believe the firearms manufacturers are solely the ones responsible for determining if and how they should market and sell a model or type of firearm. WE STRONGLY URGE YOU TO CONTACT THE MANUFACTURER OF YOUR FIREARM TO DETERMINE IF IT IS SAFE TO USE 17HMR AMMUNITION IN YOUR SPECIFIC TYPE AND MODEL OF FIREARM.
We specifically warn you: DO NOT USE 17HMR AMMUNITION IN FIREARMS IF THE MANUFACTURER OF THAT FIREARM HAS STATED IT WILL NOT SAFELY FUNCTION WITH 17HMR AMMUNITION. SERIOUS INJURY MAY RESULT.
